MACHINE FOR OPERATING ON BOOTS AND SHOES.

Application filed February 7, 1925, Serial No. 7,527, and in GermanyFebruary 9, 1924.

This invention relates to machines for operating upon boots and shoesand is illustrated as embodied in a machine of the type shown, forexample, in the copending application of Goddu and Mackenzie Serial No.628,234, filed March 28, 1923. Such machines are designed for buttingand tacking the welt of a welted unsoled shoe preparatory to thesole-laying operation and including devices for supporting the shoe,means for locatin and supporting the welt ends during the butting.operation, cutters ior butting the'welt, and tackers for securing theupper to the innersole at points adjacent to the ends of the buttcdwelt. v

In prior machines of the type above mentioned, the work supports and thewelt supports have been moved from their initial nositions into shoeengaging positions by the initial movement of a treadle, furthermovement of the treadle applying pressure to the welt supports andfinally tripping a clutch to start the machine, whereupon the followingoperations occurred automatically in proper sequence. Further pressurewas applied to the welt supports and to the work supports, the buttingknives acted to skive off the welt ends, the tackers were forced againstthe shoe adjacent to the ends of the welt, the tacks were driven and thechips cut from the welt ends were removed.

Objects of this invention are to provide a machine of the type set forthin the application above referred to which, without sacrificing any ofthe advantages of prior constructions of this type, will further re- 7duce the time and efiort required of the operator and which will beotherwise simplified and improved. Accordingly, in the presentorganization as herein shown, a treadle is employed solely for thepurpose or starting the machine, and the work supporting members aremoved by power of the machine into work supporting position inconjunction with power effected movement of the welt supports into weltsupporting position. The initial amount of separation of the weltsupports is determined by hand adjustment and the mechanism foroperating them is arranged to pick them up in any position in which theyhave been left by the manual adjustment and to apply to them apredetermined yielding pressure irrespective of their initial position.Thus, the illustrated machine is practically entirely automatic sincethe remaining operations of the machine, as in the machine disclosed 1nthe prior application above referred to, are automatic.

Further objects of the invention are to provide a machine adapted foroperation on shoes having storm welts. The term storm welt is applied toa welt formed with a thick rounded head on its outer face. This welt isattached to the shoe in the usual manner, the bead lying nextto theupper and serving to exclude water, mud and slush from the weltcrease'as well as giving an attractive appearance to the shoe.

Shoes having storm welts present new conditions for the welt butting andtacking operations which it is an object of this invention to meet.

The presence of the bead of a storm Welt in the welt crease prevents theuse of the usual crease finders or work supports, and accordingly afeature of the invention con sists in crease Ifinders having groove-s orrabbetsto receive the bead and apply pressure in the welt crease.

When the welt and bead are skived off at a sharp angle, the skivedportion of the bead projects beyond the skived portion of the welt, andif the shoe were finished in this condition the skived ends of thebeadwould be free and unsecured and would present an untidy appearance.Accordingly, a feature of the invention consists in means for turninginwardly the ends of the Welt or bead and securing them to the shoe.

In order that the skived portion of the bead may be long enoughconveniently to permit the end portion of the bead to be. turnedinwardly and tacked to the heal-seat, another feature of the inventionconsists in means for causing the inner portion of the welt end,including the bead, to be formed longer than the outer portion.

These and other features of the invention will appear more fully fromthe following detailed description when read in connection with theaccompanying drawings and will be pointed out in the appended claims.

The general organization of the machine is similar, except in therespects herein pointed'out, to that of the machine disclosed in theapplication above referred to, to which reference may be had forexplanation of parts of the mechanism not fully given herein. Theillustrated machine provides mechanism for. positioning the shoe,mechanism for supporting the shoe, mechanism for tightening the upperover the last at opposite sides of the shoe and for supporting the weltends, mechanism for simultaneously skiving off the welt ends, mechanismfor inserting tacks for securing the tacked upper to the innersole,,andmechanism for removing the out 01f ends of the welt. These variousmechanisms are mounted upon a head 2 supported upon a column l the headhaving a forwardly projecting goose-neck -6 at the front of'which are.journaled vertical pintle shafts 8 on which are pivoted swinging sideframes 12, 14. The side frames carry the welt su pports,,the weltbutting mechanism,

the chip removing mechanism and the-tacking mechanism, with theexceptionof the tack handling mechanism which is carried'by a supportingframe 16 secured to a table-18 on the upper side of the goose neck.6.

The moving parts are driven by apnlley 20 on ashaft 22 extendinglongitudinally of the'machine, said shaft carrying a spiralgear2tmeshing with a second spiral gear fixed to asleevev loose on ashaft 28 which is at right angles to the shaft 22. The loose sleeve onthe shaft 28 is rotated continuously by the gear- 24. Between thesleeve,andithe shaft 28 a clutch of the, single-revolution type is providedwhich may be tripped by a treadle 30 connected by a rod 31 to suitableclutch operatingmechanism such asthat disclosed in the prior applicationreferred to.

The actuating mechanism by which the various operating instrnmentalitiesof the machine are driven comprises connecting rod 82 one end of whichis connected with a crank 34 forming a part or" the shaft 28, theother-end of which is connected to a piston 36 arranged to reciprocateina guideway formed'centrally of the lower part of the goose-neck 6.

Connected to the forward end of the pis ten 36 is a member 38 which isformed with a horizontal slot/4O in each side. In each of the slots ablock 42 ismountcd to slide and is bored to receive a pin 4% by which itis connected to slide 46 (Fig. 7) mounted for forward and backwardmovement in the side frame. Vilhen the crank 34 rotates to draw thepiston 36 rearvm.rdly, the slides are moved to operate the welt buttingmechanism, the tacking mechanism and the chip removing mechanism, as ismore fully described in the application above referred to.

In order to position the shoefor the prop er engagement of the weltsupports in the welt crease, the machine is provided (Figs. 3 and 5}with a back gage 50 and a height 52 constructed described in said priorapplication above mentioned. This construct on is such that the rear endrest or gage 50 may be caused-to be maintained yeldingly in forward,position so that it ongages the shoe early in its movement res"- wardiybetween the welt supports and is moved by the shoe. As soon as themachine starts, the gage 50 is locked to resist rearward movement of,t-he'shoe during the action of the welt butting knives and locates itfor the tacking operation.

The forward ends of the swinging side frames 12, 14 are normally heldapart by a spring (Figs. 3 and 5) the ends of which are attached to'therear ends 62 of the r..- spective side frames at the rear of theirpivots 8. In order that the side frames mav move together they providedwith intermeshing toothed segments G l, 66, respectivcly, through whichthe, lower ends of the pintle rods-8 extend. Novelmechanism is providedfor adjusting the side frames n i at against the force ofthe spring 60and caus ing the crease finders or welt supports 70, 70, carried by theforward ends of the side frames to approach each other so that the shoemay be slipped betweenthem with the welt resting on the weit supports.This mechanism comprises a rock shaft 76 fixed to a-forwardly ext-endingarm 78. The for ward end of the arm rests on a cam 80 mounted loosely ona shaft 82 and arranged to be turned by a hand-wheel 8i, friction meansbeing preferably. provided to hold the hand-wheel and cam againstaccidental rotation on the shaft. Turning of the cam acts to rock theshaft 7 6 to which is fixed an upwardly extending arm 86 (Fig. 5). Uponopposite sides of the arm 86 near its upper end are recesses whichreceive the ends of struts 88 the outer ends of which enter cups seatedin the inner faces of the rearward projections 62 of the side frames 12,14. The struts are normally inclined so that, as the arm 86 is swungrearwardly, the struts 88 act as a toggle to separate the rear ends ofthe side frames and cause their forward ends carrying the welt supports70, to be moved toward the shoe. By turning the hand-wheel 84,therefore, the initial position of the welt supports, that is, thedistance between them when a shoe is introduced, may be varied, theadjustment being such that a shoe may be easily positioned between themwith its sole resting against the height gage 52 and its welt locatedabove the welt supports 70, 70.

From this initial position the welt sup ports are moved toward eachother by power to tighten the upper before the welt butting and tackingoperations occur. The mechanism for effecting this operation comprisesan arm 90 (Fig. 1) fixed to the shaft 76 and having pivoted to it at 92a bar 94. A rod 96 has its forward end clamped at 98 in the bar 94 andis surrounded by a spring 100 one end of which abuts against adjustingnuts 102 and the other end presses against a block 104 arranged to slidelongitudinally of the bar 94. As shown in Fig. 2, the block 104 has onits upper face a groove 106 in which a rearwardly extending rectangularportion 108 of the bar 94 is arranged to slide. The block 104 issupported on its inner face by a surface 110 formed on the machine frameand on its outer face is provided with a longitudinal groove 112 inwhich lies .a supporting roll 114 mounted on a lever 116. The lever 116is fulcrumed to the machine frame by a screw stud 118 and at its upperend carries a roll 120 which rests against an edge cam 122 secured tothe shaft 28. In the stopped position, as shown in Fig. l, the roll 120rests in a depression of the cam 122 and the lower arm of the lever 116is swung forwardly. To this lower arm of the lever below the block 104is pivoted at 124 a pawl 126 which co-operates with teeth 128 formed onthe lower face of the block 104, the pawl being raised toward the blockby a torsion spring 130 (Fig. 2) connected between the pawl and itspivot 124. In the position shown, the pawl 126 is held out of engagementwith the teeth 128 by a pawl shield 132 which is held in fixed positionon the screw stud 118 by a split clamp 134. The lever 116 is rocked in adirection to hold the roll 120 against the cam 122 by a spring 136connected at one end to the pawl pivot pin 124 and at the other end to apin 138 on the machine frame.

It will be apparent that when the machine is started by depressing thetreadle, rotation of the cam 122 will swing the lever 116 clockwise,causing the pawl 126 to pass off the stationary guard 132 and engage theteeth 128 of the block 104. Further movement of the lever will move theblock which, through the spring 100, will move the rod 96 and, throughit, the bar 94 which is connected to the arm 90. The shaft 76 willtherefore be rocked in a direction to effect separation of the rear endsof the side frames 12, 14 and cause the welt supports 70, 70 to approacheach other and apply transverse pressure in the welt crease of a shoeplaced between them.

The shoe supporting mechanism consists of a plate 140 secured to themachine flame and projecting forwardly beneath the welt supports. Theforward end of the plate 140 is forked 4) and to each branch is pivotedat 142 a lever 144. Each of these levers has an extended bearing 146 atits forward end on the plate 140 and carries a supporting pad 148. Theshoe engaging faces of these pads are inclined to correspondsubstantially to the inclination of the sides of an inverted last. arearranged to have a limited amount of free movement about vertical axes.The rear ends of the levers 144 are turned inwardly and held toward eachother by a spring 150. To cause the pads 148 to approach each other andengage the opposite sides of a shoe located between them, the inturnedrear ends of the levers 144 are engaged by a wedge 152 which is mountedon the upper end of an arm 154 fixed to the rock-shaft 82. The wedge 152is arranged to move freely in a direction at right angles to theswinging movement of the arm 154 so that whatever the lateral positionof the shoe determined by engagement of the welt supports 70, 70 in thewelt crease, the wedge will adjust itself transversely of its directionof movement to cause both pads to engage the shoe and apply equalpressure to the two sides thereof as it is moved rearwardly. Keyed tothe outer end of the rock shaft 82 is an upwardly extending arm 156 towhich is pivoted at 158 a block 160. Passing through the block is asleeve 161 adj ustably held therein by a clamp screw 163 (Fig. 1). A rod162 .passes freely through the sleeve 1.61 and is pivoted at 164 tothelower end of the lever 116. On the rod 162 be tween the sleeve 161and an adjusting nut 166 on the forward end of the rod is a spring 168.On the rod 162 at the rear of the block is an adjustable collar byadjusting which the amount of initial separation of the shoe supportingpads 148 may be varied. The initial tension of the spring 168 may Thepads 148 I HI be varied by adjusting the nut 166 on the rod 162. Theblock 160 may be adjusted along the sleeve 161 to vary the position ofthe work supports to accommodate widely different sizes of shoes withoutaffecting the initial tension of the spring 168 or other adjustments.Vhen the lever 116 is operated by the cam 122 it exerts a pull on therod 162 and acts through the spring 168 to swing the arm 156 rearwardlyand cause the shoe supporting pads to engage the opposite sides of theshoe and apply pressure thereto, the amount of pressure for shoes of agiven size being determined by the strength of the spring 168, itsinitial teu sion and the initial position of the arm 1:36.

In order to adapt the machine for handling shoes having storm wel-ts theconstruction shown in Figs. 5 to is provided. The power operated slide4-6 has in inclined sliding connection with a knife carrier 180 Fig. 7)on which a knife 182 is held by a. clamp 184. The carrier 180 has afour-motion movement given to it by the to-and-fro reciprocation of theslide 16. Projecting downwardly from the knife carrier is a pin 186which engages a cam slot in an arm 188 (Fig. 9), the pin being ofsufiicient length so that it remains in the cam slot during the verticalmovement of the knife carrier 180.

.The arm 188 is clamped to a stud-shaft 200 having a bearing in an ear202 formed on a block 204 (Fig. 10). On the shaft 200 is formed an arm206 which is forked at its end to receive a pin 210 carried by a weltpusher 212. The pusher 212 is mounted to slide transversely of themachine in a slot 213 formedin the block 1 in which it is held by a capplate 216 engaging a rabbet 218 on the pusher. The block 204 rests on ashelf 220 formed on the side frame 1 1- and is held in place by a stud222 locked by a draw bolt 224. A guard and anvil memher 226 is supportedand held on the block 204 in a similar manner by a shelf 225, a

stud 227 and draw bolt 229., as shown in F 10, and is slotted at 231 toreceive the pusher 212. The guard member 226 has a dovetailed slot 230to receive a dovetail 232 on a crease finder 234 which held in place bya. set-screw 236. The crease finder has its inner edge ra-bbeted at 238to accommodate the bead ofa storm welt. From the assembled view (Fig. 9)it will be seen that the crease finder 2341, the inner portion of thepusher 212 and anextension 240 of the guard member 226, together,constitute the welt support 70. Similar mechanism is, of course,provided on the other side frame 12 as shown in Fig. 8. The position ofa shoe in the machine and the relation of the parts of the machinebefore they operate on the shoe is shown in Fig. 5. The verticalposit-ion of the shoe is determined by the gage 52 and the degree ofseparation of the sunorts will move toward the shoe the work supports 118 being operated atthe same time to sustain the shoe.

The bead of the storm welt will be engaged by the rabbets 238 and theupper and end portions of the welt ends at the two sides of the shoeforced inwardly by the power operation of the welt supports. At thistime the pushers 212 are in normal position with their ends in line withthe vertical wall of the ra-bbet 238. As the movement of the machinecontinues the knife carriers 180 descend the pins 186 merely movingvertically in the slots of the arms 188. Then the knives moverearwardly, skiving off the welt ends on lines deter mined by theforward edges of the guard plates 240, When the knives have finishedtheir cut and while they are still positioned to hold down the endportions of the welt, the pins 186 reach the angular portions 244 in theslots of the arms 188, causing the arms to swinginwardly and tocommunicate motion through the studs 200 to the arms 202 and cause thepusher-s 212 to move toward the shoe. Th ends of the pushers areinwardly and rearwardly inclined so that when they engage'the bead andpress upon it they turn the end portions of the welt inwardly and locatethe skived ends of the head in position to receive tacks from the usualtackers 250.

The forward edge of the extension 240 of the guard and anvil memberco-operates with the knife 182 to determine the transverse line of theend of the welt. The outer portion of the welt end is cut off by theknife passing over a portion 252 of the edge of the anvil. The head,however, and the inner portion of the welt will lie over a portion 1 ofthe anvil which is farther toward the rear than theedge 252. The innerportion of the welt end, including the bead, will therefore be longerthan the outer portion of the welt. The head, because of its thickness,will, when skived, project beyond the end of the welt proper and will,by the action of the pushers 212, be turned inwardly and brought intoposition to be secured to the shoe by the tackers. The condition of theshoe after the operation of the machine, is shown in 11 in which thewelt is represented at a, the inner line of the bevel of the welt end atb, the end portion of the welt determined by the edge 252 of the anvilat c, the portion determined by the edge 254 at (Z, the propectingbeveled end of the bead at e, and the tack by which it is secured at 7".The dot-ted line 9 indicates the position of the bead beneath the weltand indicates that the end portions of the bead have been deflectedinwardly by the pushers 212 before being secured.

It will be seen that the machine organized as described is, excepttorsuch adjustments as may be requirei'l to adapt it for use on dill'erentsizes'and conditions of shoes, entirely automatic in its action. Upon depression ot the treadle to start the machine, the welt supports aremoved from their initial position to engage the shoe in the welt crease,support the welt and apply tension to the upper adjacent to the welt'ends, said tension being uniform whatever the initial setting of thewelt supports may be; the pads l lS are moved to engage opposite sidesof the shoe and apply pressure to the two sides equally notwithstandingdifferences in the shape 01" the two sides of the last and its positionas determined by the welt supports; the welt ends are skive d off by theknives 182, the ends of the welt including the bead turned inwardly bythe action of the pusher 212; tacks are driven by the tackers 250 tosecure the welt ends, and the material cut oil from the welt ends isremoved from the knives by the chip removers 260 8) which are operatedby mechanism fully disclosed in a prior application of Edward Erickson,Serial No. 335,-
